refers to the module ‘django.db.model.BigAutoField‘ that could not be imported.

django 3.2 bug

运行时报错

django.core.exceptions.ImproperlyConfigured: login.apps.LoginConfig.default_auto_field refers to the module ‘django.db.model.BigAutoField’ that could not be imported

解决方法
问题出在apps文件夹内,apps文件夹默认用于创建app专属config
Django 3.2之前默认使用的自增主键AutoField, Django 3.2及以后将会默认使用BigAutoField

from django.apps import AppConfig


class LoginConfig(AppConfig):
    # default_auto_field = 'django.db.model.BigAutoField'
    # 将上面注释掉，改成这样
    DEFAULT_AUTO_FIELD = 'django.db.models.AutoField'
    name = 'login'
